BACKGROUND

Among the existing kit tools of mop and mop bucket, there is a type of mop bucket capable of being lifted and lowered coaxially to achieve cleaning and dewatering. The cleaning and dewatering are completed by lifting and lowering the mop, for example, in the Chinese utility model Patent No. ZL201821379338.2, a self-lifting cleaning tool of a cleaning mop and a cleaning bucket separating clean water and dirty water is disclosed. The cleaning bucket is provided with a lifting device, which achieves the switch between a high position and a low position by manually pulling the mop.

DETAILED DESCRIPTION

Embodiments of the present disclosure are described below in detail in conjunction with the drawings, so that advantages and features of the present disclosure can be more easily understood by those skilled in the art, thereby more clearly defining the scope of the present disclosure.

Embodiment One

A rotary mop is as shown in FIG. 1 . The mop 1 includes a mop head 2 and a mop rod 3, and the mop head is rotatable to achieve cleaning and/or dewatering, and the rotation of the mop head is driven by a hand-pressed mop rod or a motor.

As shown in FIGS. 2 to 4 , the mop head includes a fixed plate 21 and a lifting plate 22, the fixed plate is connected to the mop rod and is rotatable, the lifting plate is connected to the fixed plate, the lifting plate is configured to move up and down relative to the fixed plate and is rotatable along with the fixed plate; and a wipe is fixedly connected to the lifting plate. It is to be noted that up-and-down movement of the lifting plate is relative to a state in which the mop head is located below.

A gap 4 is provided between the lifting plate and the fixed plate, where the gap is increasingly smaller from the center of the lifting plate to the periphery of the lifting plate; a drive member 5 is located in the gap; when the drive member is located at an end with a larger space of the gap, the lifting plate is located at a low position; and when the mop head rotates, the drive member is configured to move toward the periphery under an action of a centrifugal force and drive the gap to increase so as to elevate the lifting plate to a high position, thereby achieving the automatic lifting of the lifting plate provided with the wipe, so that operations at high and low positions can be completed without the manual lifting action.

When implemented, it is well understood that the drive member is capable of opening the gap at a certain rotational speed by adjusting a weight of the drive member, and a specific weight of the drive member is not easy to be quantified here because the weight also needs to be tested and adjusted according to a weight of the lifting plate and an accuracy (a sliding smoothness) that the product can actually achieve.

A guide groove 41 is located within the gap and configured to guide the movement direction of the drive member, the guide groove is opened at one of the lifting plate or the fixed plate, and the guide groove is oblique to form a structure in which the gap is increasingly smaller from the center of the lifting plate to the periphery of the lifting plate.

In this embodiment, as shown in FIG. 2 , the guide groove is opened at the fixed plate, and the guide groove guides the movement direction of the drive member, so that the drive member can move along an optimal path to complete the action of opening the lifting plate. Preferably, at least two guide grooves are provided, and are evenly distributed according to a rotation axis of the mop head.

In this embodiment, two guide grooves are provided (i.e., two drive members are provided), and the configuration of at least two guide grooves can achieve the balance of the mop head when rotating, and after a sample test, two guide grooves (the drive member) can well complete the action of opening the lifting plate and have no influence on the balance of the mop head and the rotation smoothness when the mop head rotates.

Preferably, the drive member is a sphere, and the sphere structure can reduce the friction when moving, so that the drive member can move smoothly.

In this embodiment, the sphere is made of metal, the metal sphere has a certain weight, and a centrifugal force of the rotation can easily move the sphere toward the periphery to open the gap.

As shown in FIGS. 3 and 4 , an elastic member 23 is provided between the fixed plate and the lifting plate, and the elastic member drives the gap to be small to make the lifting plate at the low position. That is, in a normal state, the lifting plate is located at the low position, and the elastic member may also assist in resetting the lifting plate after the lifting disk is located at the high position. In this embodiment, the elastic member is a helical spring.

As for the mop in this embodiment, the rotation of the mop head may be achieved by a hand-pressed rotary mop rod or the motor, both of which belong to the existing art, which will not be repeated.

Specific structures of the fixed plate and the lifting plate are shown in FIGS. 5 and 6 . The lifting plate 22 has a cavity 221, the fixed plate is located within the cavity, the fixed plate has a boss 211 protruding out of the cavity, and the mop rod is movably connected to the boss.

In this embodiment, the mop rod is connected to the boss by a cross shaft so that the mop head can rotate in a universal direction. The lifting plate is further provided with a panel for mounting the wipe, the panel and the lifting plate are detachably connected to each other.

A cleaning tool is as shown in FIGS. 7 to 9 . The cleaning tool includes a mop 1 and a mop bucket 6. The mop adopts the preceding rotary mop. The mop bucket is provided with a clean water area 61 and a working area 62 above the clean water area. A pump 7 is located within the clean water area and configured to pump clean water to the working area. A drive part 71 for driving the pump to work penetrates from the clean water area to the working area, and simultaneously, the drive part also forms a support part for supporting the working of the mop.

The penetrating drive part is also configured to form the support column 66 for supporting the working of the mop, the mop is supportable by the drive part to be capable of working rotatably, and an engaging part 72 is provided between the lifting plate and the drive part so as to stop the lifting plate and the drive part from rotating in a circumferential direction, when the lifting plate is located at the low position, the engaging part is configured to engage to drive the pump to work, and the pump is configured to pump out the clean water and spray the clean water on the mop; and when the lifting plate is located at the high position, the engaging part is configured to disengage to cause the pump to stop working and cause the mop to continue to rotate for dewatering.

The cleaning tool of the present disclosure does not need to be pulled manually at the time of switching between the cleaning operation and the dewatering operation, the operation of lifting and lowering the mop head is completed by adjusting the rotational speed of the mop head so as to achieve the seamless switching between cleaning and dewatering, and it also does not need to wait for the mop head to stop rotating at the time of switching, saving time and labor. During cleaning, water is sprayed by the pump to achieve good cleaning effect.

The mop bucket of the present disclosure also has a function of separating the clean water and the dirty water. The mop bucket is further provided with a dirty water area 63 which does not communicate with the clean water area and communicates with the working area, and dirty water generated by the working of the mop in the working area can flow into the dirty water area.

In this embodiment, the mop bucket includes a first bucket body 64 and a second bucket body 65 which are stacked in the upper and lower direction, the first bucket body under the second bucket body is the clean water area, the second bucket body on the first bucket body is the working area, and the clear water area is also provided with a water injection port 611.

The periphery of the second bucket body extends downward to form a receiving chamber 651. The receiving chamber is the dirty water area. and the dirty water area formed by the receiving chamber extending downwardly is lower than the working area, thus the waste water generated in the working area can automatically flow into the dirty water area under an action of gravity.

As shown in FIGS. 9 and 10 , a cleaning member for cleaning the wipe of the mop is arranged within the mop bucket, and in this embodiment, the cleaning member is a roller 8 horizontally arranged, the roller is rotatable along the axis of the roller and several tines 81 are arranged on the periphery of the roller.

When the mop is operating in the working area, the roller can form a certain squeeze with the wipe of the mop, and wastes on a surface of the wipe can be cleaned by the tines on the surface thereof. The tines in this embodiment are truncated cone shaped, and of course, the tines may also be configured to be cone shaped or cylinder shaped.

As shown in FIGS. 8 and 11 , the pump includes a pump housing 78 and an impeller 79, the impeller is sleeved on a spindle 74 fixed to the mop bucket and is rotatable, the impeller has a drive shaft 731 arranged coaxially with the impeller, the drive shaft penetrates through the clean water area and forms the drive part, and the mop head has a positioning hole 732 available for the drive shaft to insert.

In this embodiment, as shown in FIG. 11 , the impeller 73 includes a first vane 731 and a second vane 732. The second vane is located below the first vane and is arranged coaxially with the first vane, an upper end of the second vane extending upwardly until covering the first vane, a protruding part of the second vane forms the pump housing, and a water outlet speed of the second vane is smaller than a water outlet speed of the first vane.

Moreover, in this embodiment, the first blade and the second blade rotate synchronously and are both axial-flow blades, but have different blade angles. That is, different water outlet speeds are achieved through different blade angles. The blade angle refers to a water outlet angle of the blade, that is, an included angle between the blade and an end face of a wheel body. Different water outlet angles of the blades can provide different water pressures to achieve different water outlet speeds.

In this embodiment, the second blade is located below and is located at a water inlet communicating a clean water storage area and a pumping chamber for a first step of pumping. The second blade having a smaller blade angle pumps the clean water into the pumping chamber, and the first blade having a larger angle pumps the clean water out and sprays the clean water onto the mop. The first blade having the larger blade angle can provide a larger water pressure and flow velocity.

In addition, the pump housing of the pump may be configured as a conventional fixed structure, or a structure in which the pump housing rotates in synchronization with the impeller in this embodiment, and the pump housing and the second blade are formed integrally in this embodiment.

More specifically, in the present disclosure, as shown in FIG. 3 , the positioning hole includes a blind hole 7321 located on the fixed plate and a through hole 7322 located on the lifting plate. The blind hole and the through hole are arranged coaxially. When the mop is arranged at a shaft end of the drive shaft, the blind hole is used for supporting, and the lifting plate having the through hole can be lifted or lowered freely without interference.

In this embodiment, as shown in FIGS. 7 and 11 , the engaging part includes a ridge 721 arranged on the periphery of the drive part and a groove 722 arranged on an inner side wall of the positioning hole, and the ridge and the groove are capable of being engaged with each other to limit a circumferential rotation of the drive shaft and the lifting plate.

The engaged structure of the ridge and the groove is stable and can be molded for one time at the injection molding, which is easy to be manufactured.

The rotation axis of the impeller in the present disclosure is arranged vertically, a plane bearing 75 is arranged between a lower end of the impeller and the mop bucket. Since the drive shaft protruding from the impeller plays a role of supporting the mop head simultaneously, especially when using a hand-pressed mop rod in this embodiment, the impeller is subjected to a large axial force and is liable to be worn when used for a long time. The plane bearing is added, so that the rotation smoothness of the impeller is improved and the service life of the impeller is increased.

The working principle of the cleaning tool in this embodiment is as follows: the lifting plate is located at a low position when the mop is in a normal state, the mop is arranged at the drive part to rotate for working, the engaging part is configured to engage to drive the pump to pump out the clean water and spray the clean water on the mop to perform the clean operation of the mop. After cleaning for a certain time, a rotation speed of the mop head is accelerated, and at a certain speed, the drive member in the mop moves toward the periphery under the action of the centrifugal force, and the gap arranged for reduction is opened so as to jack up the lifting plate to the high position. In this case, the engaging part is configured to disengage to cause the pump to stop working and cause the mop to continue to rotate for dewatering.

Embodiment Two

The difference between this embodiment and the embodiment one is a structure of a mop bucket.

In this embodiment, as shown in FIG. 12 , the mop bucket includes one bucket body, and a support column 66 is located in the mop bucket and configured to support working of the mop. When the mop bucket is used, an appropriate amount of water is placed in the mop bucket. When a lifting plate of the mop is rotated at a low position, a wipe is in contact with the water surface, which is rotary cleaning in this case. After the lifting plate is lifted by accelerating the rotation speed of the mop, the wipe leaves the water surface, which is rotary dewatering in this case.

In this embodiment, as shown in FIG. 13 , the bucket body is further provided with a cleaning brush 68. When the mop cleans at the low position, the cleaning brush brushes the wipe surface of the mop.

Embodiment Three

The difference between this embodiment and the embodiment one is a structure of a drive member on a mop and a structure of a gap engaged with the drive member.

As shown in FIGS. 14 to 17 , in this embodiment, the height gradient gap is achieved by being arranged on an inclined surface of the lifting plate, and the whole drive member is a rectangular block, and the drive member also has an inclined surface 54 matched with the inclined surface of the lifting plate.

The spherical drive member moves mainly by rolling, which may also be accompanied by sliding. When the spherical structure is adopted, the lifting plate has a high sensitivity, that is, the lifting plate can move without a high rotation speed to achieve the drive lifting. The block-shaped drive member is slidable, and the rotation speed required by the movement is relatively high due to the influence of the friction force. In fact, there is no judgement of good or bad between the spherical drive member and the block-shaped drive member, so that they can be used selectively for different mop heads (different weights brought by different mop head types).

In this embodiment, the through hole 224 for a boss passing through on the lifting plate has an axially extended hole wall 222, the hole wall abuts a sidewall of a step, and both the hole wall and the sidewall are provided with a through opening 223, the drive member is provided with a positioning column 52 which is insertable into the through opening, and when the drive member is located at the end with the larger space of the gap (that is, the lifting plate is located at a low position), the positioning column is configured to be inserted into both through openings to lock the lifting plate.

Moreover, the drive member is provided with an elastic drive member 51 for driving the mop to move toward the end with the larger space of the gap. When the mop mops the floor, the lifting action of the lifting plate is inserted and locked by the positioning column, and the locking state is maintained by the abutment of the elastic drive member, so that the lifting plate can be prevented from shaking due to the displacement of the drive member when the mop mops the floor.

When the mop head rotates, the elastic drive member is able to impart a certain reverse pressure (damping) to the drive member, so that the movement of the drive member under the action of the centrifugal force is more uniform, which can avoid the case where the drive member moves to the bottom at once.

In this embodiment, the elastic drive member is a helical compression spring.

A structure of the drive member is shown in FIGS. 18 and 19 : a drive member body is a plastic member, and a metal weight 55 is embedded therein. A rib 53 is provided on a side of the drive member being in contact with the fixed plate to reduce the friction force when the drive member moves. The process of making the plastic drive member into various shapes is mature and the cost is low. In this embodiment, the embedded weight (interference fit) is cylindrical and thus is relatively convenient to produce.

In addition, in this embodiment, as shown in FIGS. 17 and 19 , a stopper structure is further provided on the side of the drive member being in contact with the fixed plate, the stopper structure includes a stopper protrusion 56 arranged in the drive member and a stopper groove 212 arranged in the fixed plate, the stopper protrusion can slide in the stopper groove, and sequentially restrict a movement trajectory of the drive member.

Embodiment Four

The difference between this embodiment and the embodiment one is a partial structure of a mop bucket and a structure of a mop cooperatively used together.

As shown in FIGS. 20 to 20 , the mop bucket includes one bucket body 67. The bucket body has a partition plate 671 and a cover plate 69. The partition plate 671 separates an inner chamber of the bucket body into a clean water area and a dirty water area. The cover plate 69 which can be detachable connected is arranged above the clean water area. The working area is above the cover plate. The cover plate just covers the clean water area, so that the working area can communicate with the dirty water area.

The mop used in this embodiment is the mop in the embodiment three, a cleaning member is a cleaning brush 68. The cleaning brush is fixedly connected to a bottom of the working area.

The cleaning member in the present disclosure may employ various cleaning components known in the existing art, including a cleaning blade, a cleaning brush, a cleaning rod and the like. The cleaning blade is a plate-like or block-like protrusion.

In addition, a water outlet 76 (an opening for spraying water into the mop) of the pump in this embodiment is different from that in the embodiment one. The water outlet in this embodiment is only a through opening. The water outlet in this embodiment is provided with a guide structure for guiding the water. A direction of spraying water is adjusted by the guide structure, so that the mop can be sprayed (cleaned) better.

Embodiment Five

The difference between this embodiment and the embodiment one is a structure of a pump.

As shown in FIG. 23 , the pump includes a piston pump 77. The piston pump is connected to a drive part 71 and is driven by the drive part.

In this embodiment, the piston pump includes a pump body 774 and a piston rod 771, the piston rod is located at one end of the hollow pump body, the other end of the pump body is provided with a water inlet 7741 and a water outlet 7742, the water inlet 7742 is provided with a one-way valve which is restricted to be a water inlet only, and the water outlet 7741 is provided with a one-way valve which is restricted to be a water outlet only. When the piston rod pumps the water, the clean water enters the pump body from the water inlet 7742. In this case, the water outlet 7741 is blocked by the. When the piston rod pressurizes water, the water in the pump body is discharged from the water outlet 7741. In this case, the water inlet 7742 is blocked by the one-way valve.

More specifically, both ends of a connecting rod 772 are hinged to the piston rod 771 and an eccentric wheel 773, and the eccentric wheel is connected to the drive part through a gear mechanism, so that the rotation movement is converted into the linear movement by the eccentric wheel mechanism.

In this embodiment, both the support part and the drive part both are rotatable support column, and the gear mechanism includes a driving gear 775 located at a lower end of the support column and a driven gear 776 arranged on the periphery of the eccentric wheel. The driving gear and the support column are formed integrally, and the driven gear and the eccentric wheel are formed integrally.

In this embodiment, as shown in FIG. 24 , a working area is further provided with a swash holder 681. A cleaning member is arranged on a swash holder, the swash holder has multiple water spray ports 682, all water spray ports are directly below a wipe of the mop, and a water outlet of the pump communicates with the water spray ports so that the water pumped by the pump can be evenly sprayed on the mop.

A mop bucket in this embodiment is divided into areas (a clear water area, a working area and the like). Alternatively, a single bucket without being divided into the areas may be provided, and the pump is arranged in the single bucket to complete the water-spray cleaning operation.
